We stayed on the fourth floor overlooking the blue & white striped tent area. We did not find it noisy as long as the balcony doors were shut. Since it was quite cool when we were there (last December, they were shut unless we were on them watching IlumiNations - the holiday tag was just awesome. Never seen anything quite like it)! Hope they do it again. We were always up long before the first boat horn (kids, LOL), so that didn't bother us at all. Don't even remember hearing it.
Best wishes -
